Abstract

Encompassing 44 % forest cover across a diverse elevational gradient (sea level to 2500 m asl) and encompassing biomes ranging from semi-arid to temperate rainforests, Georgia, a country within the Caucasus biodiversity hotspot, presents an unexploited opportunity for dendroclimatological research. This study assesses the suitability of Common Yew (Taxus baccata) for dendroclimatic reconstruction in Georgia. We develop the first dendrochronology in Georgia’s Batsara Nature Reserve by obtaining the species' single master chronology, analyzing the relationship between annual tree-ring growth and climate, and reconstructing past climate over the last 445 years. Results indicate that the average wintertime temperature is the most important climatic driver for the formation of the annual rings, with narrower rings corresponding to colder winters and delayed spring onsets. The reconstructed temperature aligns more closely with rural Northern Hemisphere land surface temperature records, suggesting minimal influence from urbanization bias (aka the urban heat island effect). This study demonstrates the suitability of Common Yew for dendrochronology and dendroclimatology in the Caucasus region.
普通红豆杉(Taxus baccata)作为气候档案:重建格鲁吉亚(高加索)200年的温度变化
格鲁吉亚是高加索生物多样性热点地区的一个国家,森林覆盖率为44% %,跨越不同的海拔梯度(海平面至2500 米),包括从半干旱到温带雨林的生物群落,为树木气候学研究提供了一个未开发的机会。本研究评估了普通红豆杉(Taxus baccata)在乔治亚州树木气候重建中的适用性。通过获取该物种的单一主年代学,分析了树木年轮生长与气候的关系,并重建了过去445年的气候,在格鲁吉亚Batsara自然保护区建立了第一个树木年代学。结果表明,冬季平均气温是年轮形成最重要的气候驱动因素,年轮越窄,冬季越冷,春季越晚。重建的温度与北半球农村陆地表面温度记录更接近,表明城市化偏差(又称城市热岛效应)的影响最小。本研究证明了高加索地区普通红豆杉在树木年代学和树木气候学上的适宜性。
